Lab 9 Homework: 1. (Ch 17) Describe why the force is greatest at 2.0-2.2 um length shown below 2. Draw and explain the force-velocity curve. Include an explanation of how the force per actin-myosin bond affects the force velocity curve. What role does the force generated from an individual actin-myosin crossbridge and titin play in the concentric, isometric and eccentric force-velocity relationship? (Page 229-231) .*Be detailed. 3. Describe a stretch-shorten cycle and why you jump higher with it. *Be detailed. Can draw diagrams as necessary. 4. (Ch 18) Define a motor unit. 5. Explain what is happening in this figure: 6. Explain what is happening in this figure and how you would anticipate the order of de- recruitment to happen. Be detailed. 7. In this figure (page 259) explain why the EMG and torque curves look the way that they do. **Be detailed. 8. (Ch 19) Describe a stretch reflex. **Be detailed. 9. (Ch 20) What is a Sensory Organization Test (SOT) and what are its conditions
